STOP-MOTION FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 552,149, dated December 31, 1895. Application filed February 24, 1890. Serial No. 341,482. (No model.)

To all whmn it may concern:

Be it known that I, FRANCIS SEYMOUR, of Paterson, Passaic county, State of New J ersey, have invented a new and useful Improvement in StopWIotions for Spinning Mechanism, of which the following is a full, true, and exact description, reference being had to the accompanying drawing.

This invention relates to an improvement in stop-motions in spinning mechanisms for spinning, doubling and respinning silks or other fibers which are frictionally driven from a friction-wheel, its object being to provide means for automatically checking the spinning process should the thread be broken through any cause.-

My invention will be readily understood from the accompanying drawing, in which A represents the driving-shaft; B, the friction-wheel; O, a spindle or spindles driven from the wheel B by a friction-wheel D. The friction-wheel D is mounted upon a frame having a horizontal pivot E and is over-.

weighted so as to normally fall away from contact with the driving-wheel B. It is held in contact by spring F. The spring F is held in its stretched position by hook G hooking upon plate H. In the operation of such spinning mechanisms the thread passes from the bobbin through the faller-eye K to spindle C and is wound thereon by the motion com municated through shaft A and friction-wheels B and D. The thread from the spindle 0 passes through faller-eye K. hen the thread breaks, the

faller-eye K falls in contact with the lever L 3 5 pivoted to hook G, as shown, thereby depressing the outward end of said lever. The shaft A is provided with cam M, which ordinarily does not strike the inward end of lever L; but when said inward end is raised the cam M strikes the same, releases the hook G from the plate H, and thereby releases the tension of the spring, allowing the friction-wheel D to fall out of contact with the driving-wheel B.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of the driving shaft A, the driving wheel B attached to the shaft, the cam M also attached to the shaft, the wheel D driven frictionally from the driving wheel, the pivoted frame supporting said wheel D, the spring F holding the wheels B andD in contact, the faller eye K through which a thread runs, the hooked lever G, and the two armed
